All measurements were taken at the drive power connector. A true RMS meter is used to measure all modes except Standby. A DMM is used for Standby measurements.

1.11.1.1 Active mode

During the Active mode, the drive is involved in spinup, seeking or read/write activities. The table on page 11 shows the typical power-con- sumption rates for these activities.

∙Spinup. The drive enters the Spinup mode from the Standby mode and brings the spindle and discs up to operating speed. Power in this mode is defined as the peak power after starting spinup.

∙Seek. The drive enters the Seek mode from the Idle mode. The read/write heads are moved to a specific location on the disc surface in preparation for reading from or writing to the disc. Read/write electronics are powered down but servo electronics are active. Typical power is defined as the power average of executing random seeks with a 2-revolution (22.2 msec) dwell between Seek commands.

∙Read/write. Read/write mode is entered from Idle mode. Read/write electronics are activated and the servo is on track. The drive reads from or writes to the disc.

1.11.1.2 Idle mode

The Idle mode is entered 1 minute after the last disc I/O activity. The motor is up to speed and the actuator is repositioned once every minute. This mode uses an algorithm that minimizes head media interface stresses. The drive can enter Idle mode from either Active or Standby mode.

1.11.1.3 Standby mode

The spindle is stopped, the heads are parked in the landing zone, the actuator is latched and some of the drive electronics are powered down.

Note. When recovering from Standby or Sleep mode, you must allow the drive to post ready before reporting a timeout. The drive can take up to 20 seconds to post ready. In a master and slave configuration, the master can wait up to 31 seconds for the slave to complete diagnostics before posting ready.

1.11.1.4 Sleep mode

The sleep mode implementation is the same as in Standby mode.
